1 / 13 page MP20045 Low Noise, 1A Linear Regulator MP20045 Rev. 1.0 www.MonolithicPower.com 1 10/13/2010 MPS Proprietary Information. Unauthorized Photocopy and Duplication Prohibited. © 2010 MPS. All Rights Reserved. The Future of Analog IC Technology DESCRIPTION The MP20045 is a low-dropout linear regulator supplies up to 1A current with 140mV dropout voltage. The output voltage is set externally which ranges from 1.5V to 5V by operating from +2.5V to +5.5V input or can be preset internally from 1.5V to 5V. An internal PMOS pass element is used to allow a low 110µA ground current, making the MP20045 suitable for battery-power devices. Other features include low-power shutdown, short-circuit and thermal protection. The MP20045 is available in 8-pin QFN (3mm x 3mm) and SOIC8E packages. FEATURES • Up to 1A Output Current • Low 140mV Dropout at 1A • Low 110µA Ground Current • Fixed Output Versions Ranging from 1.5V to 5V and Adjustable Versions • Open Drain Power-Good Status Output • 13µVRMS Low Noise Output • 56dB PSRR at 1kHz • Current Limiting and Thermal Protection • 3mm×3mm QFN8 and SOIC8E Packages APPLICATIONS • Notebook Computers • Cordless Telephones • Cellular Phones • Modems • Hand-Held Instruments • PDA and Palmtop Computers “MPS” and “The Future of Analog IC Technology” are Registered Trademarks of Monolithic Power Systems, Inc.
